You may come across an error message when using the SYNKii Classroom on your android phones.
"Close any bubbles or overlays from other apps. Then try again."
If you are trying to launch the classroom and you receive this message, use the following steps:
Navigate to Apps.
Navigate to Settings, and then tap Apps.
Navigate to Special access.
Tap More options (the three vertical dots), and then tap Special access.
Tap Apps that can appear on top or Draw over other apps.
Tap Appear on top, and then locate the app(s) that use an overlay. Tap the switch next to them to disable the overlay permission.
Apps that display bubbles, chat heads, or alter screen colours are frequently the source of this warning.
